GAS-RANGE.

SPECIFICATION forming part of Letters Patent No. 560,330, dated May 19,1896.

Application filed October 30, 1895. Serial No. 567,425. (No model.)

Beit known that l, ROBERT S. STEPHEN- SON, a resident of Allegheny,inthe county of Allegheny and State of Pennsylvania, have invented a newand useful Improvement in Gas-Ranges; and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to gas-stovesthat is, to the class of stoves heatedby gaseous fueleither a permanent gas or a gas or vapor generated fromhydrocarbons in connection with the stove itself,

The object of the invention is to form a compact stove and reduce thenumber of burners and cost necessary for heating the different parts,such as for broiling, heating water, and the ordinary cookingoperations.

My invention comprises certain details of construction, all of whichwill be fully hereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I-willdescribe the same more fully, referring to the accompanying drawings, inwhich Figure lis a longitudinal section on the line 2 2, Fig. 2,illustrating the invention. Fig. 2 is a top or plan View of the same.Fig. 3 is a cross-section on the line 3 3, Fig. l; and Fig. 4. is anenlarged view of the connection between the burner and the stove-body.

Like letters .indicate like parts in each.

The invention is illustrated in connection with the end portion of anordinary gas stove or range, only that portion containing the particularparts being shown or the part shown forming in itself the entire stove,if desired. The stove has the body portion having the front and backwalls a a', side Walls b b, top Wall c, and bottom wall o', the topbeing formed of the regular top plate for the stove, and being eitheropen or closed vfor cooking operations as found desirable. Below the topplate is the chamber d, which contains the water-heating coil e, formedof a series of return-pipes extending in through the back wall a towardthe front wall a and having any desired number of bends, the coil beingsupported by passing through holes in the back wall and being held by asuitable bridge e', which, in the preferred construction, is attached tothe side walls b b' at e2 by suitable screws or bolts, the coil beingheld thereto by a suitable clamp-plate es bolted to the bridge. Belowthe chamber d and separated therefrom by the deieeting-plates fandburners g is the broiling-chainber h, the chamber having the doors 7Land having a series of supporting-ribs h2, providing for the support ofthe broiler h3 at any desired height. The burners g are mounted betweenthe water-heating chamber and the broiler-chamber, and are what might betermed revolving burners, being horizontal cylindrical burners somounted that their jet-oril'ices can be turned into one or the otherchamber, so that their heat may be applied directly to the waterheatingcoil or used directly for broiling in the lower chamber.

The burners are illustrated as mountedin the following way: In the backwall or back plate a is the seat or depressed annular bearing g, whileextending through the front wall is the bearing g2, and the rear end ofthe burner is mounted in the seat g', while its front end extends outthrough the bearing g2 and carries the mixing-chamber t', the end of theburner being threaded, as at fi', and the mixing-chamber screwed thereonoutside of the stove-body, so that-when the burner is turned or rotatedthe mixingchamber is turned wthit. The miXin g-chamber has the ordinaryair-inlet openin gs 'is and has the central opening i4, through whichthe jet-pipe 7o leading from the gas-supply pipe k' passes, thegas-supply pipe with its jet-pipe being supported by any suitablebrackets from the stove-body and the mixing-chamber turning around thejet-pipe vas the burner is turned to bring its jet-openings in one orthe other chamber. To rotate the burner, as' Well as to secure it inplace, I employ the collar m., which engages with the end of thecylindrical burner by means of a key ttin g in a keyway, and is heldfrom longitudinal movement by means of a bolt m passing through a lip m2on the collar, the collar being slipped onto the burner, the forward endof the burner passed through the bearing g2v and the rear end thenslipped into the seat g', and the col- IOO lar then slipped along, so asto bear against the inner' face of the front plate a, and being held inplace by the bolt m', so preventing the burner from slipping out of therear seat g. The mixer t' can then be secured upon the burner and thegas-supply pipe adjusted in place. The collar m has the cogged face o2,with which the rack-bar j) engages, the rack-bar having on each side ofits racked 0r cogged face guide-faces p and brackets p2 withinwardlyprojeeting lips p3, being se cured to the stove-body andsupporting the rack-bar p in proper position over the burners, so thatit Will engage therewith, andl as the bar is moved longitudinally willin turn impart to the burners a partial revolution, which will bring thejet-orifices into the upper or the lower chamber as desired, the rackbarextending out through the end wall Z) and having the handle 1)".

In order to hold the heat Within the lower or broiling chamber, and toprovide for the spreading or deiiectin g of the iiame from the gas-jetsin such way as to insure the proper defiecting of the heat from theflame down upon the meat or other substance supported on the broiler, Iemploy the deiiecting-plate f, which, as shown, its between the burnersg and on the outer sides thereof for practically the full width of thebroiler-chamber. lVhen the jets are turned down so that the flame iswithin the broiler-chamber, the flame strikes upon this plate andspreads out over the same so as to give a flamesurfaee for almost'thefull width of the broiler-chamber, so utilizing the full heat forbroiling, and, as shown by practical use, largely increasing the heatingaction of the gases for broiling purposes. The

-delecting-plate may be made in sections and supported in any suitableWay, but it is preferable to cast it to shape and to connect the innersection fand outer sections f2 bymeans of curved straps f3 extendingover the cylindrical bodies of the burners, as shown in Figs. l andbrackets lr at each end, which are secured to the inner section f.

Vhen my improved stove is in use, the normal position of the burners iswith their jetorifices s in the upper chamber d., so that the fiamestrikes directly upon the Watei-l1eating coil e and provides for theheating of the Water, the heat from the flame or the flame itself, whenit is turned sufciently high, `passing through the coil and rising tothe top plate c or through the cooking-openings therein, so providingfor both the heating of the Waterand for the ordinary cooking operationsTo support the plate, I employ on the top of the stove by means of thesame burner. Then it is desired to broil or perform like cookingoperations in the chamber h, it is only necessary to push or pull uponthe rack-bar p, which, by its engagement with the cogged faces of thecollars secured to to cylindrical burners, causes the partial revolutionor turning of the burners, so as to bring the jet-orifices s within thelower or broiling chamber 7L.A The flame from the burners is then spreadout along the under face of the defiecting-plate f, and on aeccount ofthe breadth of the flame provides for a much more even heating of thebroiler-chamber and dclection of the heat down upon the meat or othersubstances within said chamber, while the deiiectingplate by holding theflame within the chamber causes a large increase of heat therein inproportion to the amount of gas burned, none of the heat being lostexcept that which passes by conduction through the deflecting-plate, andsuch heat as itrises within the waterheating chamber (Z acting to heatthe water in the coil located therein. As so arranged, I am thereforeenabled to utilize the single burner or set of burners for performingthe three operations of broiling, water-heating, and the ordinarycooking on the top plate, and I therefore do away with the necessity ofseparate burners for one or the other purpose and reduce the size of thestove while improving it in adaptability to the various uses required.

Vhat I claim as my invention, and desire to' secure byLetters Patent,is-

l. A gassteve having a revolving cylindrical gas-burner mounted inbearings therein, said burner having openings within one-half of itscircumference, a de ecting-plate on each side of said burner in linewith the diameter thereof, substantially as set fort-h.

2. A gas-stove having two cylindrical hori zon tal revolving burnersmounted therein, said burners having openings formed therein withinone-half of their circumferences, anda delecting-plat-e formed insections fitting between and on the outer sides of the burners in linewith the diameter thereof, curved straps connecting the sections, andbrackets seen red to the plate and to the stove-body, substantially asset forth.

In testimony whereof I, the said ROBERT S. STEPHENsoN, have hereunto setmy hand.
